Summary Returning false from onsubmit with image maps doesn't suppress coordinates

There is apparently a common idiom for suppressing the submission of coordinates from an image map which doesn't work in WebKit. This bug report is taken from [1]. Reproduces in Chrome nightly and Safari. [This is a common idiom] to work around imagemap behavior: onsubmit="this.submit(); return false;"> This prevents submit.x and submit.y from showing up in the resulting URL (because the browser, when the image is clicked, appends to the URL the X and Y coordinates of the pixel clicked within the image) Here is your example, modified to capture this usage: <html> <head> <script> function f() { return false; } </script> </head> <body> <form method="GET" action="/" onsubmit="this.submit(); return f();"> <input type="text" name="test"> <input type="image" src="dummy.gif" alt="Submit" title="Submit" /> </form> </body> </html> The following browser/OS combos exhibit the symptom described by the original poster in my testing, using exactly the code above: * Chrome 9.0.597.19 on Ubuntu 10.04 x86 (Firefox 3.6.13 works as expected) * Chrome 9.0.576.0 on recent Windows XP (IE8 works as expected; FF 3.6.13 passes x=0, y=0 regardless of where clicked) * Chrome 10.0.612.1 on Windows 7 Home Premium (IE8 and FF 3.6.13 work as expected) Both returning false directly in the onsubmit action, as well as calling a function that returns false, produce the symptom. These references contain workarounds using CSS or Javascript: stackoverflow.com/questions/1244009 www.webmasterworld.com/html/3545351.htm Unfortunately, they are workarounds that sidestep using images as a "image" input types, and do not address the underlying "return false" issue.

Looks like a duplicate of bug 13012, or one of the many other bugs we track on nested submission.
